A portion of a map prepared by the US Geological Survey, based on data from several Mars missions, showing the geological features of the Martian north polar region. According to its creators, this map is the first to record the pole's entire observable stratigraphic record using the various post-Viking image and topography datasets. The full map and key can be found on the USGS web site at pubs.usgs.gov/sim/3177/
